KUFRA BASIN PDF

To view the data for individual basins, select a basin from the dropdown menu below or click the basin name in the overview table. This will open a separate page with detailed maps. Click here to return to the regional overview page. This page bundles the available data for the Al Kufra Basin in the Africa. The images are hyperlinks and will open up a separate window with a high resolution PDF image of the map. The basin data is derived from a lower resolution grid which has been upsampled using GMT.

This page bundles the available data for the Al Kufra Basin in the Africa. The images are hyperlinks and will open up a separate window with a high resolution PDF image of the map. The basin data is derived from a lower resolution grid which has been upsampled using GMT. This could have introduced an accuracy which is beyond the original data resolution.

The basin cross section is automatically generated using the available crustal structure data sets. Sometimes the data labels are not plotted correctly, depending on the length of the section.

The location of the profile is indicated in all maps as dashed-dotted thin black line. For the endpoints of the profile, the two points of a given polygon located farthest away from each other were computed. The dynamic topography history for the basin is derived by tracking the basin centroid.

The paleo-location for this point is computed using the EarthByte plate kinematic framework rotating the position back in time. The density anomalies are then advected back in time to compute mantle flow with plate motions superimposed using the EarthByte plate rotation framework as surface boundary conditions. The dynamic topography is then derived from the computed density distribution using a free upper boundary. For details regarding the methodology see the following papers: B.

Steinberger, H. Schmeling, and G. Large-scale lithospheric stress field and topography induced by global mantle circulation. Earth Planet. Effects of latent heat release at phase boundaries on flow in the Earth's mantle, phase boundary topography and dynamic topography at the Earth's surface.

We'd like to understand how you use our websites in order to improve them. Register your interest. Across the Saharan platform, mudrocks of latest Ordovician—Silurian age the Tanezzuft Formation are a major source rock interval for Palaeozoic petroleum systems, but source rock quality is variable and difficult to predict. In the Kufra Basin of southern Libya, evidence for organic enrichment in this formation is scarce.

Kufra Basin Project

At the end of nineteenth century Kufra became the centre and holy place of the Senussi order. It is located in a particularly isolated area, not only because it is in the middle of the Sahara Desert but also because it is surrounded on three sides by depressions which make it dominate the passage in east-west land traffic across the desert. For the colonial Italians, it was also important as a station on the north-south air route to Italian East Africa. These factors, along with Kufra's dominance of the southeastern Cyrenaica region of Libya, highlight the strategic importance of the oasis and why it was a point of conflict during World War II. The folk etymology associaters the word Kufra as coming from the Arabic word kafir , the Arabic term for non-Muslims often translated as "infidels", literally "those who conceal [the truth]" , with reference to the Toubou people native to the region.
